BUG: XSS Security flaw in BaseCamp Messages (via) BaseCamp lets users include HTML and JavaScript in messages, on the basis that anyone with a BaseCamp account is a trusted party. I’m not convinced: you could use this to circumvent BaseCamp’s access control stuff and read messages you’re not meant to. On the flip side, you could also use this to add brand new features to BaseCamp by using JavaScript in a message as a server-side equivalent to Greasemonkey.
